Si-COAT® 528™ Remarkable® Low VOC Spray Grade Anti-Graffiti Protective Coating

1 of 9 products in this brand
Si-COAT® 528™ Remarkable® Low VOC Spray Grade Anti-Graffiti Protective Coating is a permanent (non-sacrificial) one coat anti-graffiti protective coating. It is available in a variety of colors, and dries to a semi-gloss finish. It is suitable for use over metal, concrete, brick, stone, wood, fiberglass and pre-existing coatings. This single component, room temperature vulcanizing (RTV), moisture cure polysiloxane anti-graffiti protective coating provides excellent durability and long service life. It can easily be applied using brush, roller or airless spray equipment. As a result of its specific chemistry, Si-COAT 528AG Remarkable Low VOC forms chemical bonds with the host surface to enhance adhesion properties without the need for abrasive blasting, priming, and extensive site preparation. Due to the hydrophobicity of the coating, most graffiti-tagging can easily be removed from protected surfaces using water under low pressure. For best results, graffiti tagging should be removed from Si-COAT 528AG as soon as possible using a cold water pressure washer at 1200 psi.

Product Characteristics
  • Surface finish is dependent on application method. Avoid using a combination of application methods whenever possible. Superior esthetic appearance will be obtained with airless spray application.
  • If over coating Si-COAT 528AG after prolonged weathering or aging, ensure the coating is fully cleaned to remove all surface contamination such as dust, grease, oil, salt crystals, traffic fumes, etc. before application of a further coat of Si-COAT 528AG.
  • Do not apply to substrate temperatures below 41°F (5°C). When applying Si-COAT 528AG in confined spaces ensure adequate ventilation and/or respiratory equipment is available. Consult the Si- COAT 528AG SDS for further details.
  • Si-COAT 528AG has excellent tolerance to airborne chemical exposure. When severe chemical or solvent splashing/pooling is likely to occur please contact CSL Silicones Inc. for information regarding suitability.
Benefits
  • Environmentally Responsible, Low VOC.  Exceeds the requirements of California's South Coast Air Quality Management District (AQMD) for reduced environmental impact.
  • Easy Application - Single coat, can be applied using airless sprayer, roller or brush.
  • Quick Dry Time - Tack free in 60 minutes; cure time 4 - 6 hours.
  • Superior Performance & Durability – Permanent, water cleanable and UV resistant. Graffiti can be washed off using a pressure washer (1200 psi) or soft bristle brush and water.
  • Versatile - Use on most metal, concrete, brick, stone, wood, fiberglass and pre-existing coatings.

Surface Preparation & Cleanliness

All surfaces to be coated should be free of dirt, dust, chalking paint, mortar spatter, all loose rust, all loose mill scale, old caulking, grease, oil, release agents, curing compounds, laitance and other foreign matter including frost.

Coating Application

Mixing

Si-COAT 528AG is supplied as a one-part coating (no component mixing necessary). Mix by an air powered agitator (300 – 400 rpm) for a minimum of 5 minutes, to ensure an even consistency of coating is obtained without air in suspension.


Application

All surfaces should be clean and dry prior to application. The coating should be applied in a manner that prevents runs, sags, drips, spills, etc. and that completely covers surfaces without holidays (gaps). The temperature of the surface to be coated should be between 41°F and 140°F (5°C and 60°C) and environmental & substrate temperature should be at least 5°F (3°C) above the dew point prior to and during application. When working with Si-COAT 528 AG in high humidity and/or high-temperature environments, it is recommended to use a pail lid adapter fitted with an agitator. This will prevent the product from skinning over and curing in the pail during application. It is recommended that Si-COAT 528AG is applied using an airless sprayer; however, brush, or roller are also suitable methods of application for small surface areas. It is necessary to apply at a rate that will achieve a minimum of 5 mils (127μ) DFT. Roller and brush application will require multiple coats to achieve desired DFT even if the coverage is adequate.


Graffiti Removal

For best results, graffiti tagging should be removed from the Si-COAT® 528AGTM coating as soon as possible using a cold water pressure washer at 1200 psi. In the instance that graffiti has been left on for a longer time period (greater than 10 days) and is stubborn to remove with cold water then a warm water pressure wash may be necessary. In the extremely rare instance that stubborn graffiti media (specialty paints with adhesion primers that have been left to cure for extended periods of time) is not removed 100% with warm water then apply a biodegradable surfactant (dish soap) with a cleaning pad and rinse off immediately. Note: Before applying cleaner to the coating, test a small patch in an inconspicuous area. Contact CSL Silicones Inc. for information and/ or recommendations on which cleaners are most suitable for specific problems.


Thinner

Equipment Cleaner

CSL901 Equipment Cleaner, Naphtha or Odorless Mineral Spirits.


Work Stoppages & Restarts

Work stoppages are not recommended with only partial utilization of a container of Si-COAT 528AG. If work must stop after only a portion of a container of Si-COAT 528AG is used, seal to minimize air and moisture contact with the coating by covering the surface of the coating with a sheet of polyethylene film, then reseal the container to be airtight. Upon reopening the container to restart work, peel back the polyethylene film. If curing of the coating has occurred, use a utility knife to cut the cured coating away from the wall of the container. Peel away the cured layer of coating to expose fresh coating underneath.


Clean-up

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with Si-COAT equipment cleaner, naphtha or mineral spirits. Fully cured coating is environmentally benign (will not harm) and is suitable for landfill disposal. However, always check local environmental regulations before disposal.

Systems Compatibility

Although no primer is needed prior to applying Si-COAT 528AG to most common substrates, it is recommended to do a quick field adhesion test prior to application.
